Microwave-Assisted Hydrothermal Method HTMW

The hydrothermal method is known as one of the most usefiil synthesis procedures, not only in the preparation of perovskite-type oxides. Generally, this

1[12] BiFeOs (BFO) Hydrothermal (HTMW) Microwave furnace with frequency of 2.45 GHz and variable power up to 300 W Different soaking times 5 min, 30 min. and 1 h at the temperature of180°C Uniform nanoparticles with very few structural defects, homogenous size distribution, and orthorhombic structure were observed 

2 [13] BiFeOs (BFO) Hydrothermal (HTMW) Adapted microwave oven The microwave reaction was carried out at 200 C for 5,15,20, 30, 40,50, 60,70, and 80 min All samples are mostly composed of particles with a quasi-spherical morphology 

3 [14] CaTiOs (CT) Hydrothermal (HTMW) Microwave system with frequency of 2.45 GHz and with a maximum output power of 800W The reaction mixture was heated to 140 C in less than 1 min (at 800 W) by a direct interaction of wat widi microwave radiation and was kept at this temperature for 10,20,40, 80, and 160 min under pressure of 2.5 bar Microcube-shaped powder with orthorhombic structure was observed. The disorder coupled to the tilt of TiOg-TiO ad acoit octahedra was mainly responsible for the photoluminescent emission
